Plato documents Socrates’ final days in four books all written as dialogues. The first dialogue, ensuing shortly before Socrates’ trial for impiety and corruption of Athenian youth occurs between Socrates and the Athenian prophet, Euthyphro, who together attempt to define piety without success.

The second book, Apology, Socrates defends himself to the Athenian court, poorly in all respects, purposefully one suspects, confessing that his life’s quest is one of seeking wisdom, nothing more.

Crito is the third book in this series, and it takes place in Socrates’ prison cell after he has been found guilty of his crimes with his execution scheduled for the next day. Crito, a wealthy friend of Socrates, has come to urge him to escape. Socrates refuses and the ensuing dialogue revolves around justice and the damage to one’s soul through the actions of injustice.

In the fourth book Phaedo, a Greek philosopher, visits on the day of Socrates’ execution, and has a discussion centered on the immortality of the soul. Socrates offers four arguments for why the soul must be eternal while the body is mortal, firmly imprinting the duality of nature into the human psyche for endless generations to come.
